We are currently working into integrating the new Validator Key API standard into Stereum. Currently our efforts mainly are Lighthouse, as it is one of first and were critical in the definition & implementation of the standard. The new standard certainly simplifies the whole process, while keeping the same functionality. We are happy to see that the whole space is getting better and better, allowing us to get the most out of it for Stereum. We also added monitoring for Lighthouse and Nimbus last week.
There were many other smaller changes, like every week, you can find this change and follow our development on GitHub.
